BCG claims to be the world's top creator of custom GPTs, with over 36,000 built.
Boston Consulting Group has built an internal R&D lab and a three-layer AI product assembly line to create custom GPTs for client work and internal operations.
BCG runs a 3-layer pipeline where private firm data feeds agents, consultants prototype tools on live cases, and a central team ships hardened versions firm-wide.
The older consulting pattern tends to leave value stuck in one-off slide decks, bespoke scripts, and advice that is hard to reuse, audit, or maintain across teams.
BCG’s bottom layer tries to fix that by wiring AI agents to a private library of presentations, documents, and reports, so the hard part becomes selecting the right internal data at the right moment, not just calling a big model.
